The train blew past buffers as it arrived at Once, shortly after 10 a.m. GMT, and ended up wedged between the floor and ceiling of the platform. The cause of the crash remains under investigation.

The line the train was on came from Moreno, which is roughly 25 miles west of Buenos Aires. The train is operated by a company called Sarmiento, and is typically a very busy and overcrowded commuter line.

According to Security Secretary Sergio Berni, some commuters waiting on the platform were injured by flying glass from the train's windows.

Jorge Ramirez, a chef and train passenger, said, "I saw people hurt, shouting, others thrown on the floor. The people in the first wagon ended up piled on top of each other."

In related news, in late September, two Chicago Transit Authority trains wrecked into one another in Forest Park, crushing part of at least one train car and sending several people to local hospitals. The investigation into the cause of that accident is still underway.

Earlier this month, a logging truck collided with a passenger train in West Virginia, killing one man, and injuring 20.
